Mathilda Avenue Improvements at SR 237 and US 101

The Project is located in the City of Sunnyvale from Almanor Avenue/Ahwanee Avenue to Innovation Way, including on- and off-ramp improvements at the SR 237/Mathilda Avenue and US 101/Mathilda Avenue interchanges.  

The design features of the Project include reconfiguration of the US 101 and SR 237 interchanges with Mathilda Avenue. This includes modification to on- and off-ramps; removal, addition, and signalization of intersections; and provision of new left-turn lanes. In addition, the Project would require modification to bicycle and pedestrian facilities, utilities, stormwater treatment facilities, street lighting, ramp metering, signage, retaining walls, and light rail crossing facilities as described.


Objective

To reduce congestion on Mathilda Avenue, improve mobility for all travel modes, and provide better access to local destinations throughout the City of Sunnyvale.
